COIN-E JE CTOR FOB IVZIISIG AL INSTRUMENTS.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed. August 26, 1907. Serial No. 390,155.

To all whom it may concern:

Be it known that I, WILLARD E. CLEVE- LAND, a citizen of the UnitedStates, residing at Oregon, in the county of Ogle and State of Illinois,have invented certain new and useful Improvements in Coin-Ejectors forMusical Instruments, of which the following is a specification.

The object of this invention is to positively eject a coin therebystopping the action ofthe instrument.

In the accompanying drawings, Figure 1 is a face representation of aportion of the frame of a musical instrument to which I have a plied myimprovements. Fig. 2 is a vertica section through the casing for theoperative parts, in which the top plate of insulating material isremoved, and in which the coin is shown in operative position. Fig. 3 isa similar section in which the coin is to be forcibly ejected. Fig. 4 isa transverse section on dotted line a@ Fig. 2.

The frame 1 of the musical instrument is formed with a coin chute 2. Acasing is secured to the frame and comprises the back 3, edges 4, top 5and front 6.

To the back 3 of the frame is secured a plate 7 of insulating material,and some dis tance from this plate 7 is located a support 8 ofinsulating material to which are con nected two binding posts 9 and 10,the screw sections of which rest in contact with the plate 7 ofinsulating material in order that they may be insulated from the casing.From the face of this support 8 of insulating material project twosections 11 and 12 over which is located a face plate 13 of insulatingmaterial and held in contact therewith by the nuts 14 applied to thebinding posts 9 and 10.

To the face of the support 8 are secured two metallic plates 15 and 16held separated some distance' The plate 15 has an outturned edge 17. Awire 18 connects the plate 15 with the binding post 10, and a wire 19connects the plate 16 with the binding post 9.

To the support 8 of insulating material is pivoted a coin ejectorcomprising the coin rest 20, ejecting finger 21, weighted tail section22 and tripping extension 23.

To the casing is secured a pneumatic 24,

and to the movable section 25 of this pneumatic is secured an arm 26.

A tube 27 is intended to connect the pneumatic with a valve chamber of amusical instrument, the valve in the chamber controlled by a note sheetpassing over a tracker-bar in the well known manner. An exhaust pump isintended to connect with the valve chamber in order that the air may beexhausted from the pneumatic.

The weighted tail section 22 holds the coin ejector in the positionshown in Fig. 2, so that the ejecting finger will rest against theadjusting screw 28. The wires 29 and 30 connect the binding posts 9 and10 with the electric motor.

When a coin 31 is placed in the coin chute 2 it will descend between thesupport 8 and face plate 13 and will be supported by the coin rest 20and outturned edge 17 of the metallic late 15, and will also restagainst the metallic plate 16. The coin will form an electricalconnection between the plates 15 and 16 thereby starting the electricmotor, which will set the operative parts in motion to render the music.

After the note sheet has moved on the trackenbar until the piece ofmusic is finished, an opening in the note sheet will coincide with anopening in the tracker-bar, which will open the valve in the valvechamher and permit the pump to exhaust the air from the pneumatic 24which action will move the arm 26 against the tripping section 23 of thecoin ejector, thereby moving the coin ejector on its pivot and cause theejecting finger 21 to force the coin down and permit it to drop into thecoin receptacle 32. The motor will immediately stop, and stop theoperation of the instrument. The weighted tail section 22 will returnthe coin ejector to its normal position. The adjusting screw 28 is usedto properly locate the coin ejector so that a coin will pass theejecting finger 21 and stop on the rest 20.

The weighted tail section 22 will return the movable section 25 of thepneumatic 24 into .its normal or expanded position.

I claim as my invention.
